Abstract

In this paper, we present a fast intra prediction method based on separating the transformed coefficients. The
prediction block can be obtained from the transformed and quantized neighboring block generating minimum distortion
for each DC and AC coefficients independently. Two prediction methods are proposed, one is full block search
prediction (FBSP) and the other is edge based distance prediction (EBDP), that find the best matched transformed
coefficients on additional neighboring blocks. Experimental results show that the use of transform coefficients
greatly enhances the efficiency of intra prediction whilst keeping complexity low compared to H.264/AVC.
